The current code only disables those IRQs that we will later use. To
ensure that we have a predefined state, we really want to disable all IRQs.
Change the code to disable all IRQs to achieve this.

There are two places inside mtk_poll_rx where rx_dropped is not being

The QDMA engine can fail to update the register pointing to the next TX
descriptor if this bit does not get set in the QDMA configuration register.
Not setting this bit can result in invalid values inside the TX rings
registers which will causes TX stalls.

During stress testing, after reducing the threshold value, we have seen
TX timeouts that were caused by the watchdog_timeo value being too low.
Increase the value to 5 * HZ which is a value commonly used by many other
drivers.

The lookup of the tx_buffer in the error path inside mtk_tx_map() uses the
wrong descriptor pointer. This looks like a copy & paste error. Change the

This series contains various small fixes that we stumbled across while
doing thorough testing and code level reviewing of the driver. The only
patch that sticks out is the first one, which addresses a DQL related
issue. The rest are just minor fixes.
John Crispin (12):
net: mediatek: fix DQL sup
The MTK ethernet core has 2 MACs both sitting on the same DMA ring. For
DQL to be deterministic it needs to track the amount of data in the DMA
ring and not the amount of data enqueued on each device. The current code
is incorrect, fix it by making it each device track its own traffic aswell
as the
The logic to calculate the threshold value for stopping the TX queue is
bad. Currently it will always use 1/2 of the rings size, which is way too
much. Set the threshold to MAX_SKB_FRAGS. This makes sure that the queue
is stopped when there is not enough room to accept an additional segment.

Scratch memory gets allocated in mtk_init_fq_dma() but the corresponding
code to free it is missing inside mtk_dma_free() causing a memory leak.
With this patch applied, we can run ifconfig up/down several thousand
times without any problems.

When the NFIT provides multiple flush hint addresses per-dimm it is
expressing that the platform is capable of processing multiple flush
requests in parallel. There is some fixed cost per flush request, let
the cost be shared in parallel on multiple cpus.
Since there may not be enough flush hint
Flushing posted-write queues is now deferred to REQ_FLUSH context, or
otherwise handled by an ADR event at the platform level.

The __pmem address space was meant to annotate codepaths that touch
persistent memory and need to coordinate a call to wmb_pmem(). Now that
wmb_pmem() is gone, there is little need to keep this annotation.

nsio_rw_bytes() is used to write info block metadata to the namespace,

Given that nvdimm_flush() has higher overhead than wmb_pmem() (pointer
chasing through nd_region), and that we otherwise assume a platform has
ADR capability when flush hints are not present, move nvdimm_flush() to
REQ_FLUSH context.

Since flush hints are a per-dimm property and we want to start using
them outside of block-window I/O context, move their initialization to
nvdimm_probe() context.
For the future use of flush hints in the pmem driver it would be
unfortunate to call back into the bus provider just to issue a write,
The pcommit instruction is being deprecated in favor of ADR
(asynchronous DRAM refresh) flush-on-power-fail, required at the

nvdimm_flush() is an alternative to the x86 pcommit instruction. It is
an optional write flushing mechanism that an nvdimm bus can provide for
the pmem driver to consume. In the case of the NFIT nvdimm-bus-provider
nvdimm_flush() is implemented as a series of flush-hint-address [1]
writes to each

Before enabling use of flush hints for pmem regions, we need to make
sure they are always associated. Move the initialization of nfit_flush

There are scenarios where we need a middle ground between disabling all

As VFS expects, i_count.counter field should be incremented when the named inode
is found.
